System Design

1. System Introduction 

 1. This system is the off-line spiral ultrasonic testing system.

2.  Testing step

2.1: Work piece will be neatly put onto the platform.

2.2:Work pieces will be put onto the orbit by the mechanical hand ,and then the workpiece will spiral move to the testing area, begin to test.

2.3: when find defects, the instrument will automatic alarm, at the same time it will display the flaw signal.

2.4 :record and analyse the test results , automatic sort the qualified and unqualified, and then finish the detection 

2.Testing object: seamless pipe , steel bar

3.Testing material : Carbon steel ,stainless steel,copper,aluminium,titanium and different kinds of non-ferrous and ferrous metals

4. Testing speed : 0-4m/min

5. Testing model : Workpiece spiral forward, testing  probe immobilization

6. Testing Standard :

ISO 9303:1989---- Seamless and welded (except submerged arc-welded) steel tubes for pressure purposes —Full peripheral ultrasonic testing for the detection of longitudinal imperfections

ISO 9305:1989---- Seamless steel tubes for pressure purposes — Full peripheral ultrasonic testing for the detection of transverse imperfections
